A source-Arron or MARYLAND SIDE AND JOURNAL BOX Application filedFebruary 15, 1927. Serial No. 168,338.

This invention relates to side frames for railway trucks and, moreparticularly, to such frames of the type in which each journal boxcomprises a portion formed integral with or rigidly connected to theside frameand a movable portion which can be opened or moved intoinoperative position with respect to said rigid portion.

The principal object of my invention, generally considered, is toprovide atruck side frame with journal boxes associated therewith, eachjournal box comprising upper and lower portions resiliently heldtogether.

An object of my invention is, the provision of a cast steel side frameformed with the upper portion or top half of each journal box castintegral therewith and the lower. portion or. bottom halfv piv-otallymounted with respeot to the frame and means provided for resilientlyholding the free side of said pivoted portion ofthe journal box againstthe corresponding. portion of the upper part thereof.

Another object of my invention is the prov vision of a journal box inwhich the lower portion thereof is relatively shallow or closely spacedwith respect to an associated journal for bringing. and holdinglubricating material close to said journal for properly lubr cating thesame.

A further object of my invention is the provision of a ournal box formedwith ribs preferably positioned one on either side of an associatedjournal and extended inwardly. and sloped downwardly to adjacent saidjournal for preventing the waste or other. lubricating material fromcreeping up. and causing overheating due to lubricating material bindingbetween the journal and its bearing.

A still further object of my invention is the provision of a journal boxin which the bottom thereof is coaxial with the associated journal,thereby keeping the waste or lubricating material from settling downaway from the journal. i i

d An additional object of my invention is the provision of a journal boxformed in two parts, the upper part thereof being integrally or rigidlyconnected with an associated frame and the lower part being. resilientlyheld to said frame and pressed upwardly against the upper part toconstantly'hold lubricating means therein in place against an associatedjournal regardless of the wear thereof. Y

Other objects and advantages ofthe invention relating to the particulararrangement and combination of the various parts will beframe andjournal box.

Referring to the drawings in detail, and first considering theembodiment of my invention illustrated in Figures 1 to 7, inclusive,like parts being designated by like ref erence characters, I have showna side frame 1 which may be of generally conventional construction andcomprise a compression member 2 and a tension member 3 spaced atintermediate portions thereof by bolster guide column or strut portions4:. These members may be generally U shape in cross section or of otherdesired configuration.

In the present embodiment of my inven tion, the frame is provided with ajournal box 5 at each end thereof, said journal box being formed in twosections or halves, an upper section 6 and a lower section 7. Al thoughin Figure 1 only one half of the side frame and associated boxes areshown yet it will be understood that the frame is symmetrical and a boxis provided at each end thereof. Although in the present embodiment theupper portion or half 6 of the journal box is shown integral with theadjacent part of the side frame yet, as will be understood. it may, ifdesired, be formed separately and rigidly or otherwise connected to theside frame in any desired manner, for example, as shown in the PatentNo. 1,585,522 of May 18, 1926, to Donald S. Barrows entitled Journal boxfastening means.

The upper or integral portion 6 of the journal box 5 may be of generallyconventional interior construction and provided with the usual brasslugs 8. The dust guard wall v or pocket 9, however, may be formedwithout the usual upper opening for reasons to be hereinafter explainedmore in detail. The side frame may be extended entirely over the roof ortop wall of the journal box 5 and continued down over the outer wall, asindicated at 10, terminating in a flange or web 11 between the sidewalls thereof, to define a pocket 12 adapted for receivingresilientmeans 13 for holding the lower part 7 of the journal box in properposition against the upper part 6; The inner side wall 14 of the journalbox maybe rigidified and connected with the adjacent portion of thetension memher by a pair of longitudinally extending webs or triangulargusset portions 15. These webs are, in the present embodiment, providedwith registering apertures 16 and inwardly extending bosses 17 aroundsaid apertures for increasing the bearing area therein.

The lower or movable portion 7 of the journal box 5 is preferablypivotally connected with respect to the upper portion 6 of said journalbox by a bolt or the like 18 extending through registering apertures ina pair of hinging lugs or ears 19, preferably integral with said lowerportion 7, and the apertures 16 in the webs 15 heretofore referred to.Said bolt may be headed at one end and the other end provided with a nut20 and locking device 21 for preventing loss of said nut. The lowerportion 7 of the journal box is adapted to telescopically orinterlockingly engage the upper portion 6 thereof and, for that purpose,has its side walls continued so that they normally extend above thelower edge of the side walls of the upper portion 6 and are adapted toeventually engage abutments 22 on said side walls. The free edge or sideof the movable portion 7 of the journal box is formed with anoutstanding flange or lip 23 perforated for the reception of the bolt orpin portion 24: of the resilient means 13. Said resilient means 13, inthe present embodiment, is shown as comprising the bolt 24: providedwith a head 25 at its upper end and a coil or helical spring 26surrounding said bolt and positioned between the web 11 of the frame andthe head 25 of the bolt to thereby resiliently urge said bolt upwardly.The lower end of said bolt 24 extends through the perforated lip 23 onthe lower portion 7 of the journal box and is threaded for theapplication of a nut 27 thereon. Said nut may be formed with lugs 28adapted to engage corresponding grooves in the seat of the'lip 23 forpreventing undesired rotation thereof.

In the present embodiment, the lower portion of the pivoted section 7 ofthe ournal box is curved beneath the associated journal 29 coaxiallywith respect thereto so that waste or other lubricating material betweenthe same and the journal is kept in operative engagement with saidjournal and prevented from settling away from the same as has happenedwith other forms of ournal boxes. Extendin g inwardly from the sides ofthe lower portion 7 of the ournal box are ribs or flanges 30 whichpreferably continue to almost the associated journal 29, the innerportions thereof sloping downwardly to prevent oily waste or otherlubricating material from creeping up around the journal and binding,thereby obviating undue heating. The sloping of the ribs 30 downwardlyand inwardly also serves to drain oil back to the lower portion of thejournal box. From a consideration of Figure 6, particularly, it will beseen that the flanges or ribs 30'are curved at their ends, as indicatedat 31, to. conform with the shape of the. journal.

Positioned between said journal 29 and the top of the journal box 5 areabrass 32 and a Wedge 33 which may be of conventional form. The uppersurfaces of the ribs. 30 are normal ly spaced from the lower surfaces ofthe side walls of the upper portion 6 of the journal box a distancecorresponding with the spacing between the stop portions 22 and the'topof the movable portion 7 of the journal box thereby allowing a desiredamount of upward movement upon wearing of the. journal and brass. Thisupward movement is automatically effected by the spring 26 pulling up onthe bolt 24, the nut 27' and free side of the pivoted portion 7 of thejournal box, whereby said pivoted portion and the contained lubricatingmaterial is constantly held in place against the journal regardless ofwear.

The dust guard well or pocket 9 is formed in two parts, that is, the topportion thereof is provided in the rigid part 6, of the journal box andthe bottom portion is formed in the movable or swinging part 7 thereof.Any

desired dust guard may be. positioned in said pocket but, in accordancewith the present embodiment of my invention, I propose a two part dustguard 84, both of said parts, however, being interchangeable andsimilarly formed if desired. Each part 35 may comprise a semi-circularpreferably metallic collar portion 36 preferably U. shape in crosssection as shown particularly in Figure 5.. The

' ends of said collar portions are bent away from each other asindicated at 37 and both of said semi-circular collars areadvantageously lined with felt or other similar material 38, the ends ofsaid felt sections being riveted or otherwise connected to the free ends37 of the collars 36 as indicated particularly at 39. For urging. saidcollar sections and particularly the felt lining thereon into operativeengagement with the journal 29, bent leaf springs 40 are provided,advantageously con.- nected with the collar portions 36by rivets. or thelike 41 and formed at their. ends with curved portions 4 2 respectivelyengaging. the top and bottom walls of the journal box 5 whereby the sameare urged together and into operative engagement with the journalthereby effectively sealing the inner open ng 43 of the journal box. Onaccount of the lower portion of the journal box being made movabledownwardly, the dust guard may be inserted upwardly into place beforethe lower portion ofthe ournal box is moved into position therebyobviating the necessity of: providing the usual top opening above thedust guard well.

' The outer opening 44 in the journal box may, if desired, be formedentirely in the upper or rigid section thereof, and, in the presentembodiment, is shown closed by a lid 45 pivoted to a ournal box hingelug 46 by means of a hinge pin or pintle 47 extending through anaperture in said lug and corresponding registering apertures in thehinge ears 48 of the lid. A flat spring 49 riveted or otherwise suitablyconnected to the lid at 5.0 is shown which is adapted to hold the lid ineither. open or closed positions by engaging suitable angularly disposedfaces on the lug 46 in a well understood manner. The lower edge 51 ofthe lid is disposed so as to overlap the upper edge of the pivotedportion 7 of the ournal box and form a tight seal therewith. A usualform of lip 52 may be provided on the. lower edge of they lid forconvenient manipulation thereof.

Although I have shown the movable portion 7 of each journal box as acasting yet it is to be understood that my invention is not limited tosuch construction for, if desired, said portion may be formed of pressedmetal as it merely serves for housing the lubricating material and isnot normally subjected to excessive strains or shocks in service.

Referring now to the embodiment of my invention illustrated in Figures 8and 9, I have shown an end portion of a side frame 1 provided with ajournal box 5, said journal box being formed, as in the previousembodiment, in two sections or halves, an upper section 6 and a lowersection 75*. In the present embodiment, the upper section of the journalbox is shown integral with the adjacent part of the frame but, aspreviously explained, I do not wish to be limited to such construction.

The upper or integral portion 6 of the journal box may be of generallyconventional construction and correspond substantially to that shown inthe first embodiment except that, if desired, the roof may be formedwith sloping end portions 53, as illustrated. The side frame ispreferably extended'entirely over the roof or top wall of the journalbox 5 and continued down over the end wall as indicated at 10 taperingto finally merge with said end wall, as illustrated. A flange or web 11is preferably formed between the side walls of the side frame 1providing a pocket 12 adapted to receive resilient means 13 for holdingthe lower part 7 of the journal box in proper position against the u perpart 6*. The inner side wall 14 of the journal box may be rigidified andconnected with the adjacent portion of the tension member of the sideframe by longitudinally extending Webs or triangular gusset portions 15These webs, as in the preceding embodiment, are preferably provided withregistering apertures receiving a bolt or other pivoting means 18 formovably mounting the lower portion 7 a of the journal box 5 with respectto the side frame 1, said pivotal means 18 preferably extending throughhinging lugs or cars 1 9 desirably formed integral with the The lowerportion 7 of the journal box is adapted to telescopically or interlockinly engage the upper portion 6 thereof and, for that purpose, has itsside walls continued so that they normally extend abovethe lower edge ofthe side walls of the upper portion 6 and are adapted to engageabutments 22 on said side walls. Extending inwardly from the sides ofthe lower portion 7 of the journal box are ribs or flanges-3O whichpreferably continue to almost engage the associated journal 29,diagrammatically illustrated, as in the previous embodiment for asimilar purpose. Extending upwardly from intermediate portions of saidribs 30 are flanges 54 which lie inside of the site wall portions of theupper half 6 of the journal box and, together with the upper portions ofthe side walls of the movable half 7 form pockets 55 whichtelescopically receive the lower edge of the fixed portion 6" of thejournal box. Defiecting ribs or flanges 56 are preferably provided onthe fixed portion 6 of the box extending downwardly and inwardly overthe flanges 54, illustrated.

The free edge or side of the movable portion 7 of the journal box is, inthe present embodiment, formed with outstanding lugs or ears 23perforated for the reception of a bolt or pin 24. Said bolt is adaptedfor engagement with the resilient means 18, hereinbefore referred to,and particularly with the keeper or perforated head portion 25 thereof.Extending upwardly from the keepor portion 25 is a threaded extension orbolt portion 57 extending through an aperture in the web 11, surroundedby a helical spring or other resilient means 26 and supplied with a nut27 at its upper end. The side walls of the side frame, adjacent the nut27, are preferably provided with inward exten sions 58 which come soclose to the nut 27 that they prevent appreciable turning thereof andthereby lock the same in position after assembly.

A preferred method of assembling the movable portion 7* of the journalbox with the frame and rigid portion thereof is as follows. The pivotbolt or pin 18*" is inserted to mount said movable portion 7 withrespect to the frame 1 as in the previous embodiment. The resilientmeans 13 is then connected to the frame by first ia'iserting theextension or bolt portion 57 through the apertured web 11 of the frame,applying the spring 26 thereof and the nut 27' thereon, said nut beingtightened to the requisite c.egree by turning the keeper or head portion25 rather than by turning the nut, said nut being held in positionbetween the extensions 58 of the frame. It will be noted that the keeperor head portion 25 is formed with an aperture 59 adjacent its lower endand the free edge of the movable portion 7 of the box is formed with acorresponding pocket or indentation 60, the purpose of which is tofacilitate insertion of the bolt 24. The movable portion 7 of the lid,after filling the same with waste or other lubricating material, isswung to the position indicated in Figure 9, and a bar, piece of pipe orother lever means 61 inserted through the aperture 59 into the pocket 60whereby suificient leverage is obtained to compress the spring 26 untilthe transverse aperture in the keeper 25 is alined with thecorresponding apertures in the ears 23 of the box when the bolt 24 isinserted to the position indicated in Figure 8. After insertion, thelever means 61 may be removed releasing the spring 26, whereby thehinged portion 7 of the lid is resiliently held against the upperportion 6 thereof. After insertion, the bolt 27 may be prevented fromundesired removal by means of the hairpin cotter or the like 62.

Referring now to the embodiment of my invention illustrated in Figures10 and 11, there is shown a portion of a side frame 1 with a ournal box5 comprising an integral upper portion 6 and a removable lower portion 7swingingly mounted, as heretofore, at its inner edge by a bolt 18extending through hinging ears 19 on the lower half 7* of the journalbox and webs 15 on the frame. The journal box, in general, may besubstantially identical with that of the first embodiment illustrated inFigures 1 to 7, inclusive. The free or swinging edge of said box,however, is provided with spaced outstanding flange or web portions 68connected at their upper edges by a web portion 23" forming a pocket 64receiving resilient means 13 for connecting said movable portion of thebox to the frame.

The adjacent end of the frame l is similarly formed, that-is, the sidesthereof are extended below the roof portion of the box and formed withinwardly extending'tlange or ledge portions l1 forming abutments againstwhich the upper end of the resilient means 13 is adapted to engage. Saidresilient means, in the present embodiment, comprises a bolt 24 formedwith a head 25' and encircled by a spring 26' engaging the head at itslower end and the web portion 23 at its upper end. The upper end of thebolt 24 is threadably mounted in a socket portion 65 which, in turn, ispivoted to a link 66, the upper end of said link being connected to atensioning lever 67 by means of a rivet or other pivotal means 68.

The manner of resiliently holding the swinging portion of the boxagainst the upper portion, it is thought, will be clear from theforegoing but in order to avoid any possibility of misunderstanding, itmight be stated that, after pivotally mounting the inner edge of the boxportion 7 by means of the bolt 1.8,

the resilient means 13 is connected thereto by inserting the bolt 24?with the spring 26 therearound through the aperture in the Web 23 andthreadably connecting the socket thereto by turning said socket, thehead 25 of the bolt being prevented from turning by engagement betweenthe webs 63. After threading the bolt into the socket 65 to the desiredextent, the lever 67, held in an inverted position with respect to thatshown in Figure 11, is moved toward the end of the frame P, the link 66being inserted in the slot formed between the ledge portions 11 and thelip portion 69 and the lever engaging the corresponding lip portion 70on the frame. Upon rotating the lever 67 clockwise to the position shownin Figure 11, it will be apparent that the pivotal connecting means 68is raised, correspondingly compressing the spring 26* and holding thepivotally mounted portion 7 of the box resiliently against the fixedportion 6 thereof, as illustrated in the drawings. When in the positionillustrated, the lever 67 is prevented from release by the flat lowersurfaces 71 thereof on the bifurcated pivoted end engaging thecorresponding upper surfaces of the ledges 11 and resiliently heldthereagainst.

Referring now to the embodiment of my invention illustrated in FiguresBand 13, a construction very similar to that shown in Figures 8 and 9 isdisclosed except that the engagement between the corresponding edges ofthe fixed portion 6 of the box 5 and the swinging portion 7 E thereofcorresponds more nearly with that of the first embodiment. As in theembodiment illustrated in Figure 8 and 9, however, the resilient means13comprises a bolt portion 24 surrounded by aspring 26 and provided with anut 27. The nut 27 is normally engaged between the extensions 58 fromthe sides of the frame 1 whereby undesired rotation thereof isprevented. The lower end of the bolt 24 is provided with a bifurcatedhead 25, the sides of which are provided with registering aperturesreceiving a rivet or other pivoting means 72 to "connect a link 73therewith. Said link is preferably formed with outstanding lugs 74 atintermediate portions thereof and is adapted to extend between spacedlugs 75 on the swinging portion 7 of the journal box with the lugportions 74- engaging therebeneat-h for holding the spring 24: stressedfor resiliently pressing the pivoted portion 7 c of the box against thefixed portion 6 thereof.

In order to conveniently compress the spring 26 so that theengagementbetween the lugs 74 and 75 can be effected, the lower end of the link 73is preferably apertured as indicated at 76 for receiving a bar or otherlever means 77-, one end of which is adaptedto engage a hook or otherfulcrum 7 8 provided on the swinging portion 7 c of the journal box andthe opposite end manually operated.

From the foregoing, it will be seen that, in order to connect theresilient means 13 for resiliently holding the parts of the boxtogether, the bolt 24 is first inserted through the correspondingaperture in the web portion 11 connecting the sides of the frame 1, thespring 26 inserted thereover and the nut 27 applied to the end thereofand threadably mounted thereon by turning the bolt 24?, said nut beingprevented from turning by engagement between the extensions 58 will beunderstood. hen the nut has been tightened to a sufficient extent, theswinging portion 7 c of the box is moved to closed position and theapertured portion 7 6 of the link 73 and the hook or fulcrum portion 78engaged by the lever means 77 to stress the spring 26 and permit movingthe link 73 until the lug portions 74 thereon engage the correspondinglugs 7 5 on the swinging portion of the box.

Referring now to the embodiment of my invention illustrated in Figures14; and 15, a construction is there disclosed which quite similar tothat of the preceding embodiment in that the swinging portion 7 d of thebox 5 is held against the fixed portion 6 thereof by resilient means 13involving a bolt 2d extending through a corresponding aperture in theweb 11 connecting the sides of the frame 1 said bolt 24 having mountedthereon a spring 26 retained in place by a nut 27 The head 25 of thebolt, however, is not bifurcated but merely perforated and alink 7 3connected thereto by rivet or other pivoting means 7 2, said linkcomprising spaced arms 74 joined by a connecting portion providing anaperture 76 for receiving 3 baror other lever means 77. The link (3 isadapted to fit over an outstanding lug 7 5 on the box and the spring 26is stressed until engagement between the lug and link can be readilyeffected by inserting the lever 77 111 the aperture 76 and correspondingpocket providing a fulcrum 78 in the box and applying force thereto aswill be under stood. For preventing undesired release of the link 73from the lug 75, saidflug is preferably notched as indicated at 79 andthe cooperating portion of the. link similarly formed. I

The resilient means l3 may be applied in a manner slmilar to thatdescribed in connection with the preceding embodiment but the frame 1 isshown unprovided with extensions cooperating with the nut 27 to preventturning thereof so that said nut is preferably castellated, asillustrated, and provid-ed with a retaining cotter 80. One advantage ofsuch a construction is that the spring can be tightened by merelyturning the nut 27 without removing the link 73 from engagement with thelug 7 5 Referring now to the embodiment of my invention illustrated inFigures 16 and 17, a construction is there disclosed which is verysimilar to that shown in connection with the as illustrated.

embodiment illustrated in Figures 8 and 9. The journal box 5 asheretofore, comprises an upper portion 6 permanently or rigidlyconnected to the frame 1 and a lower portion 7 pivotally mounted on saidframe by means of a hinge pin 18 extending through hingin ears 19 on thelower portion of the box and web portions 15 on the frame. The it )perportion of the box comprisesa lower edge portion telescopically receivedin pockets 55,-" formed at the upper portion of the movably mountedlower portion 7 of the bo by the upper portions of the side wallstheredt and the inwardly spaced flanges 5& extending upwardly from thesloping web portions 30. The movably mounted lower port-ion i of the boxi substantially concentric with the associated journal (not shown)lthough it is not ex ctly so as will. be apparnt from a consideration ofthe drawings and is provided with a flattened portion 81.

The free or outer edge of the movable portion 7 of the box is formedwith cars 23 corresponding generally with the pivoting ears 19 andperforated for receivlnga connecting pin 2 E. Said pin 24 lsreceived inregistering apertures 82 formed in the outer portions of the side wallsof the frame 1 below the connecting web portion 11 adapted to supportresilient means 13 for continually urging the movably mounted lowerportion of the box toward the upper portion.

From aconsideration of the foregoing, it-

will be seen that the pin 24 provides a safety connecting meanscorresponding to the plvot pin 18 for holding the movable portion of thebox under the fixed portion thereof. In order to perform the doublefunction of preventing undesired release of the pin 24 and alsoresiliently hold the lower portion 7 of the box, resilient means aremounted on the web portion 11 of the frame, heretofore refcrr" l to,said means eon'iprising, in the present embodiment, a helical spring 26directly resting on the web portion 11 and supporting, at its upper end,a bearing block 83 formed with an aperture 84 thcrethrough, the lowerside of which is flattened and adapted to rotatively receive acorrespond-- inely flattened pin 85. Said pin extends outwardly throughslots 86 in the side walls of the frame 1 and is rigidly connected withthe arms of the U-shaped latch member 87, Said latch member 87 is formerwith elongated pockets 88 receiving the ends of the pin i l and, with aconnecting portion 89, normally extending below the lugs 413 on the box.

The latch member 87 is inserted in place by con'ipressing the spring2r") in any desired manner as by inserting a bar or other lever means(not shown) above the connecting portion 89 of the latch into thecorresponding pocket providing a fulcrum for moving said latch 7downwardly and stressing the grease? spring until the ends of the pin Qislip into the openings 90 in the elongated pockets 88, whereupon saidspring may be released to draw the latch 8'? upwardly to resilientlysupport the ends of the pin 24 and thereby urge the free end of theswinging portion 7 of the box upwardly toward the fixed portion thereof.It will be appreciated that the apertures 82 in the frame 1 are so largeor elongated that they provide sufficient play for allowing the springpressure to act upwardly and support the free end of the pivoted portionof the box.

From the foregoing description, it will-be appreciated that a safetyfeature is provided in that the pin 24 cannot be removed unless thespring latch 87 is unfastened and, even ll. the so shouldv not be fullylatched, the fla tened side of the pin resting against the correspondingflattened portion of the aperture 84 tends to hold the latch against theframe through the spring pressure on the corner of the flat. The bottomloop of the latch would then still retain the safety pin in position. Ifthe spring should break, the entire latch 87 would drop straight downengaging the ends of the pin in the upper portions of the elongatedpockets 88. If desired, of course, additional means for preventingundesired removal of the pin 24 could be provided such as head on oneend and cotter means on the other.

One function of all the preceding embodiments of my resiliently heldlower half of the journal box is to utilize the same as a waste orlubricant retainer and, as it is hinged to the frame, it will not benecessary to use a separate cradle for the lubricating material assumingthat the pivotally mounted lower portion of the box will be unfastenedbefore the frame is jacked up for removal of the brass.

From a consideration of the foregoing de scription of my invention takenin connection with the accompanying drawings, it will be seen that Ihave devised an advantageous side frame and journal box constructionwhich allows free and visual inspection of the condition of the ournalupon merely dropping the lower portion of the box. The construction alsopermits the quick replacement of I wheels without dismantling the truckand facilitates the removal of a split brass even though the same maybecome locked or wedged between the journal and box. In the foregoingconstruction in which the lower half of the box is shallow andpreferably nor mally concentric with the journal, the amount oflubricating material necessary is reduced while at the same time, saidmaterial is more efficiently used because it is prevented from droppingaway from the journal yet, on account of the ribs on each side of thejournal, danger of waste or the like creeping around the journal andwedging between the same and the brass, where it would be apt to causeundue heating, is obviated. On account of the resilient means forholding the lower portion of the journal box against the upper portion,the lubricating material in said lower portion is constantly held inplace against the journal regardless of wear of the same and theassociated brass. Because of the telescoping or interlocking ointbetween the upper and lower halves of the box, dirt and other foreignmaterial may be effectively exclude -Having now described my invention,I claim:
